Decision-Making Perception Illusion of Being Attention Illusions are Everywhere! Illusion of Being There Happiness Language Memory Conscious Will
Illusions are Informative How we see it wrong -> How vision works
Visual Illusions Show Decisions • We are interested in surface colors, object shapes • But color and shape are not on the retina • We guess at color and shape

Brightness is a Decision Luminance = illumination/reflectance illumination luminance reflectance

Attention We only see what we pay attention to
Memory is an Illusion Listen to these words
Your memories change every time you remember Not “record, rewind and play”
Which were on the previous list? • Bed • Paper • Keyboard • Door • Drowsy • Awake • Doctor • Dream • Sleep • Mouse • Camera • Box • Hospital • Rest • Skin • Nurse
Illusions are Everywhere (Review) • Vision – Color/Brightness and shape are guesses and decisions • Attention – We ignore most of what is out there • Memory – We recreate our memories every time we remember
Illusions inform us of limits Image on the eye Attention Memory } Constrained, short, sparse
But we’re good enough, smart enough… To solve the common problems of human life (among the hardest engineering problems ever): • Understanding and producing human speech • Walking • Object Perception (recognizing words, faces)
